Determination of 2-Chloromethyl-Oxirane in Water by Capillary Gas Chromatography / 环境与健康杂志

Objective To make a method for determination of 2-chloromethyl-oxirane in water by gas chromatography. Methods 2-chloromethyl-oxirane in water was extracted by dichloromethane. The extraction was highly condensed.The condensate was isolated through FFAP capillary, and than was detected by hydrogen flame ionization detector. Results The linear range was 0.502-10.04 ?g/ml, r=0.999 2, the detection limit was 0.000 5 mg/ml, recovery rates were 90.3%-99.9%, RSDs were 3.5%-4.3%. Conclusion This method is simple, sensitive, accurate and suitable for determination of trace 2-chloromethyl-oxirane in soak water used for safety assessment of water supply equipments and coatings paints.
